Duncan Lake Fishing in Johnson County, Wyoming

• Overview

  Duncan Lake is set in Johnson County, Wyoming. The land about it is mixed forest. At 6 acres it is the sort of place you fish for an evening rather than a day. Most waters listed here for Johnson County are larger. Sheridan at 25 miles is the nearest place to stop. Billings is the closest city, 107 miles away. The county line is nowhere near, so one local authority covers the water.

• Where to Fish on Duncan Lake

  We hold no depth figure for this one. Bays and points beat straight shoreline every time on water like this. Weed, then depth: that is the order to fish a water of this kind. Johnson County records list brown trout, rainbow trout and brook trout among the fish reported. It is the county picture; the agency list is water-specific. Duncan Lake gives up more to patience than to distance.

• Seasonal Patterns

  Expect July near 54°F and January near 18°F on the long-run figures. The year runs cold to warm and back, with clear transitions. Hard water holds through the cold months, breaking up near late May. Climate figures give an open season running late May to mid November. Late spring and early autumn carry the year between them. The season on Duncan Lake follows the weather closely.

• Tackle & Baits

  Nothing in our records says who may fish here. No car park, ramp or path is recorded within easy reach of the shore. Largemouth respond to soft plastics tight to cover; go weedless where the growth is heavy. A phone call first saves an afternoon. Close seasons apply to some species and not others. Thayer Lake, 1.7 miles away, makes the obvious fallback. For Duncan Lake in particular, ask before you travel.
